Constanţa, historically known as Tomis, is the oldest still-populated city in Romania. It was founded around 600 BC.
Tomis (also called Tomi) was a Greek colony in the province of Scythia Minor on the Black Sea shore, founded around 600 BC for commercial exchanges with the local Getic populations.
The city was afterwards included in the Province of Moesia, and, from the time of Diocletian, in Scythia Minor, of which it was the metropolis. After the 5th century, Tomis fell under the rule of the Eastern Roman Empire.
